Hereinafter, an overview of the whole fraud detecting system in a gamehouse including a plurality of game tables according to a firstembodiment of the present invention will be described in more detail.

FIG. 1 is a diagram illustrating an overview of the whole system, thefraud detecting system in a game house including a plurality of gametables 4 includes: a game recording device 11 that records the state ofprogress of a game performed in the game table 4 as a video includingplayers 6 and a dealer 5 through a plurality of camera devices 2; animage analyzing device 12 that performs an image analysis of therecorded video of the state of process of the game; and a carddistributing device 3 that determines and displays a result ofwinning/losing of each game in the game table 4. The card distributingdevice 3 is a so-called electronic shooter that has already been used bypersons skilled in the art and has rules of a game programmed in advanceand has a structure capable of determining winning/losing of a game byreading information of distributed cards C. For example, in a Baccaratgame, winning of the baker, winning of a player, or tie (drawn) isdetermined basically based on the ranks of two to three cards, and adetermination result (a result of winning/losing) is displayed in aresult display lamp 13.

The fraud detecting system further includes a control device 14 thatcompares the rank of actual cards according to a result of the imageanalysis performed by the image analyzing device 12 and a result ofwinning/losing determined by the card distributing device 3 with eachother and detects fraud (mismatch between a sum of ranks of distributedcards and a result of winning/losing) performed in the game table 4. Thecard distributing device 3 has a structure capable of reading ranks (A,2 to 10, J, Q, K) and suits (hearts, spades, or the like) of cards Cthat are manually distributed by the dealer 5, and the control device 14has a structure capable of determining match/mismatch by collatinginformation of a rank and suites acquired by the image analyzing device12 (using artificial intelligence) from a video (captured by using thecamera device 2) of cards distributed in the game table 4 andinformation of cards and suits read by the card distributing device 3with each other. The image analyzing device 12 and the control device 14of the fraud detecting system have a structure integrally including acomputer formed as one body or by a plurality of configurations, aprogram, and a memory.

The image analyzing device 12 and the control device 14 have anartificial intelligence-utilizing or deep-learning structure capable ofacquiring information of ranks of cards also for cards C that aredistributed in the game table 4 and are bent or contaminated by theplayer 6. For a contaminated card C, as illustrated in FIG. 3, there isa situation in which it is difficult to determine clubs or spades. Alsoin such a case, the suite can be determined by an artificialintelligence-utilizing computer or control system, an analysis and adetermination of an image using a deep learning (structure) technology.In addition, also in a case where a card is bent according to a player'ssqueeze of a card, which is frequently performed in a Baccarat game orthe like, by using self-learning of examples of many deformations ofimages or the like, a suit and a rank of a card before deformation canbe recognized according to an artificial intelligence-utilizing computeror control system and a deep learning (structure) technology. Theartificial intelligence-utilizing computer or control system and thedeep learning (structure) technology are known as a person skilled inthe art and can be used, and thus, detailed description thereof will notbe presented.

The control device 14 having an artificial intelligence-utilizing ordeep learning structure can perceive a position (a player, a banker, ora pair) inside a bet area 8 on which each player 6 bets substitutecurrency 120 for gaming, the type (a value of a different amount isassigned to substitute currency 120 for gaming for each color) of thebet substitute currency 120 for gaming through the camera device 2 andthe image analyzing device 12. Not only there is a case where thesubstitute currency 120 for gaming is vertically arranged to besuperimposed but also there is a case where the substitute currency forgaming is superimposed with deviations as illustrated in FIG. 2A. Insuch a case, in a case where the camera device 2 is positioned in thedirection of an arrow X illustrated in FIG. 2A (or the direction of thesubstitute currency 120 for gaming is relatively in a blind area), asillustrated in FIG. 2B, it is assumed that the substitute currency 120for gaming is not visible (enters a blind area). According to theartificial intelligence-utilizing computer or control system or thedeep-learning technology, by using a self-learning function or the like,hidden substitute currency 120 for gaming due to a blind area or thelike is recognized (there are case where a part of one unit ofsubstitute currency for gaming is hidden or a case where the wholesubstitute currency for gaming is hidden), and the number of quantityand the like can be correctly perceived.

In this way, since a position (a player, a banker, or a pair) inside thebet area 8 on which the substitute currency 120 for gaming is bet andthe type (a value of a different amount is assigned to substitutecurrency 120 for gaming for each color) and the quantity of the betsubstitute currency 120 for gaming can be perceived, the control device14 determines whether or not collection (denoted by an arrow L) of thelosing substitute currency for gaming bet by each player 6 and payment(120W) for winning substitute currency for gaming to a player 6W who haswon are properly performed according to a result of winning/losing of agame in accordance with a result of winning/losing of the gamedetermined by the card distributing device 3 in each game by analyzing avideo of the state of process of the game through the image analyzingdevice 12. In a case where a determination result acquired through ananalysis using the image analyzing device 12 is different from a result(for example, a result of reading using an RFID) of reading using theother means, the intelligent-type control device 14 stores the analysisimage and can verify the result later. As a result of the verification,in the case of an error in the intelligent-type control device 14, byusing the analysis image as sample data of teacher leaning in thedeep-learning technology, the accuracy of the intelligent-type controldevice 14 can be improved.

The control device 14 can analyze and acquire a total amount of thesubstitute currency 120 for gaming in the tray 17 for substitutecurrency for gaming for the dealer 5 in the game table 4 by using theimage analyzing device 12 and can compare and calculate whether or not atotal amount of the substitute currency 120 for gaming inside the tray17 for the substitute currency 120 for gaming has been increased ordecreased according to the amount of collection of the losing substitutecurrency 120 for gaming bet by each player 6 and the amount of thepayment 120W for winning substitute currency for gaming to a player 6Wwho has won after the end of the game and the settlement based on aresult of winning/losing of the game. A total amount of the substitutecurrency 120 for gaming in the tray 17 for substitute currency 120 forgaming may be constantly acquired using means such as an RFID, and thecontrol device 14 determines whether or not the increased/decreasedamount is correct by analyzing the video of the state of progress of thegame through the image analyzing device 12.

For this, the artificial intelligence-type or deep-leaning structure isalso used.

In this example, since fraud or a mistake is detected based on a resultof winning/losing of a game, information of the type of bet substitutecurrency 120 for gaming, the position (a player, a banker, or a pair)inside the bet area 8 on which the substitute currency 120 for gaming isbet, and the quantity of the substitute currency 120 for gaming, and anincreased/decreased amount of the substitute currency 120 for gaming inthe tray 17 for substitute currency for gaming after the end of thecollection of losing substitute currency for gaming and the repaymentfor the won substitute currency 120 for gaming without acquiring themovement of the substitute currency 120 for gaming after the end of thegame, that is, whether the bet substitute currency 120 for gaming hasbeen moved to the player side or the dealer side.

For example, in the case of Baccarat, a result of winning/losing of agame can be determined based on rules of Baccarat by reading ranks ofcards C delivered in that game by the card distributing device 3. Inaddition, a result of winning/losing of a game can be determined also byimaging an area on the game table 4 by using the camera device 2,analyzing the image using the image analyzing device 12, and collating aresult of the analysis with the rules of the game by using the controldevice 14. In such a case, a winning/losing result determining device isconfigured by the camera device 2, the image analyzing device 12, andthe control device 14. The information of a player of each play position7, the type of bet substitute currency 120 for gaming, the position (aplayer, a banker, or a pair) inside the bet area 8 on which thesubstitute currency 120 for gaming is bet, and the quantity of thesubstitute currency 120 for gaming is acquired by imaging the substitutecurrency 120 for gaming placed on the bet area 8 by using the cameradevice 2 and analyzing the image for each play position 7 by using theimage analyzing device 12.

In addition, an increased/decreased amount of substitute currency 120for gaming in the tray 17 for substitute currency for gaming before andafter the collection of losing substitute currency 120 for gaming andthe repayment for winning substitute currency 120 for gaming can becalculated by comparing a total amount of the substitute currency 120for gaming disposed inside the tray 17 for substitute currency forgaming before the collection of losing substitute currency 120 forgaming and the repayment for won substitute currency 120 for gaming witha total amount of the substitute currency 120 for gaming disposed insidethe tray 17 for substitute currency for gaming after the collection oflosing substitute currency 120 for gaming and the repayment for wonsubstitute currency 120 for gaming.

The total amount of the substitute currency 120 for gaming disposedinside the tray 17 for substitute currency for gaming before thecollection of losing substitute currency 120 for gaming and therepayment for won substitute currency 120 for gaming and the totalamount of the substitute currency 120 for gaming disposed inside thetray 17 for substitute currency for gaming after the collection oflosing substitute currency 120 for gaming and the repayment for wonsubstitute currency 120 for gaming can be detected by imaging the tray17 for substitute currency for gaming housing the substitute currency120 for gaming using the camera device 2 and analyzing the image usingthe image analyzing device 12. In addition, by embedding an RFIDrepresenting the amount inside substitute currency 120 for gaming andarranging an RFID reader in the tray 17 for substitute currency forgaming, a total amount of the substitute currency 120 for gaming housedin the tray 17 for substitute currency for gaming may be configured tobe detected.

For example, it is assumed that the total amount of the substitutecurrency 120 for gaming disposed on the tray 17 for substitute currencyfor gaming before the start of a game is Bb, and the total amount of thesubstitute currency 120 for gaming disposed on the tray 17 forsubstitute currency for gaming after the game ends, and the collectionof losing substitute currency 120 for gaming and the re-payment forwinning substitute currency 120 for gaming is Ba. In addition, in thisgame, a total amount of all the play positions 7 of substitute currency120 for gaming that is bet on the player area is bp, a total amount ofall the play positions 7 of substitute currency 120 for gaming that isbet on the banker area is bb, and a total amount of all the playpositions 7 of substitute currency 120 for gaming that is bet on a tiearea is bt. For example, in a case where a result of winning/losing of agame is the winning of the banker, Ba−Bb=bp−bb+bt needs to be satisfied.Alternatively, the total amount Ba of the substitute currency 120 forgaming of the tray 17 for substitute currency for gaming after the endof the game needs to be (Bb+bp−bb+bt). Otherwise, it can be determinedthat there is fraud or a mistake in the collection or repayment of thesubstitute currency for gaming.

FIG. 13A is a diagram illustrating details of a tray for substitutecurrency for gaming according to this embodiment, and FIG. 13B is adiagram illustrating another example of a tray for substitute currencyfor gaming. In the tray 17 for substitute currency for gaming, acollection tray 171 for substitute currency for gaming that is used forcollecting and temporarily storing substitute currency 120L for gamingthat is bet by a losing player 6L and a repayment tray 172 forsubstitute currency 120W for gaming that is used for storing substitutecurrency 120L for gaming to be re-payed are arranged. The imageanalyzing device 12 and the control device 14 acquire the position, thetype, and the quantity of substitute currency 120L for gaming that isbet by the losing player 6L and calculates an increased amount (anamount of substitute currency 120 for gaming to be present in thecollection tray 171 for substitute currency for gaming) of substitutecurrency 0L for gaming in the game. In addition, the image analyzingdevice 12 and the control device 14 acquires a real total amount ofsubstitute currency 120 for gaming in the tray 171 for substitutecurrency for gaming after the collection and compare a total amount withthe real total amount to determine whether or not there is a differencetherebetween.

In addition, for the repayment of substitute currency 120W for gamingfor a winning player 6W, by using substitute currency 120 for gamingthat is present in the repayment tray 172 for substitute currency forgaming, a sufficient time can be secured for the image analyzing device12 and the control device 14 to acquire a real total amount ofsubstitute currency 120 for gaming in the collection tray 171 forsubstitute currency for gaming after collection.

As illustrated in FIG. 1, the game table 4 includes a disposal area 41and/or a disposal slot 42 used for disposing cards C used in a game.When a game ends, the cards C used in the game are collected and are putinto the disposal area 41 or the disposal slot 42 on the game table 4.

The game table 4 further includes a marker 43 representingwinning/losing of a game.

FIG. 4A is a plan view illustrating the front side of a marker, and FIG.4B is a plan view illustrating the back side of a marker. In a Baccaratgame, two types of a marker 43 a representing the winning of the playerand a marker 43 b representing the winning of the banker are used, and,when a result of a game comes out, the dealer 5 overturns the marker ofthe winning side out of the player or the banker. In this way,winning/losing of a game is represented on the table to be easilyunderstood. The overturned marker is returned to the original state bythe dealer 5 after the collection and the repayment of substitutecurrency 120 for gaming. By returning the marker to the original state,it also represents a state in which a next game can be started.

As above, in this embodiment, the control device 14 calculates theamount of bet substitute currency for gaming on the game table 4 and abalance of substitute currency for gaming from a result ofwinning/losing of a game for each game and verifies an increased amountof the balance of substitute currency for gaming inside the tray 17 forsubstitute currency for gaming after the game. When a difference isdetected in this verification, the control device 14 generates an alarmor adds recording of an indication thereof in the recording of a videocaptured by the camera device 2. A casino operator can peruse the reasonfor the difference by checking the video.

The fraud detecting system according to this embodiment adds/subtractsan increased/decreased amount of substitute currency for gaming in agame calculated based on the positions, the types, and the quantities ofsubstitute currency 120 for gaming that is bet by all the players 6 inthe game and a result of winning/losing of the game acquired by thewinning/losing result determining device to/from a total amount ofsubstitute currency 120 for gaming in the tray 17 for substitutecurrency for gaming before a settlement of each game, compares a totalamount of substitute currency 120 for gaming to be present in the tray17 for substitute currency for gaming after the settlement at the timeof the end of the game with a real total amount of substitute currency120 for gaming in the tray 17 for substitute currency for gaming at thetime of end of the game that is acquired through the image analyzingdevice 12, and determines whether or not there is a difference between atotal amount and a real total amount.

The control device 14 acquires the position, the type, and the quantityof substitute currency for gaming that is bet by each player through theimage analyzing device 12, acquires a real total amount of substitutecurrency for gaming placed in the tray for substitute currency forgaming when all the collections of losing substitute currency for gamingbet by each player end, compares a total amount of substitute currency120 for gaming to be present in the tray 17 for substitute currency forgaming, which is acquired by adding an increased amount in the tray 17for substitute currency for gaming in the game based on the positions,the types, and the quantities of substitute currency for gaming bet bylosing players to a total amount of substitute currency for gamingplaced in the tray for substitute currency for gaming before asettlement of each game, with a real total amount of substitute currency120 for gaming placed in the tray 17 for substitute currency for gaming,and determines whether or not there is a difference between the totalamount and the real total amount.

In a case where the control device 14 compares a total amount ofsubstitute currency 120 for gaming to be present in the tray 17 forsubstitute currency for gaming, which is acquired by adding an increasedamount in the tray 17 for substitute currency for gaming in the gamebased on the positions, the types, and the quantities of substitutecurrency 120 for gaming bet by losing players to a total amount ofsubstitute currency 120 for gaming placed in the tray 17 for substitutecurrency for gaming before a settlement of each game, with a real totalamount of the substitute currency 120 for gaming placed in the tray 17for substitute currency for gaming, and determines that there is nodifference between the total amount and the real total amount, andcompares a total amount to be present in the tray 17 for substitutecurrency for gaming after the settlement at the time of end of the gamewith a real total amount of substitute currency 120 for gaming placed inthe tray 17 for substitute currency for gaming at the time of end of thegame acquired through the image analyzing device 12, and determines thatthere is a difference between the total amount and the real totalamount, the control device 14 determines a mistake in the payment andgenerates a payment error signal used for giving a notification of themistake in the payment.

In the tray 17 for substitute currency for gaming, the collection tray171 for substitute currency for gaming that collects and temporarilystores substitute currency 120 for gaming bet by losing players isarranged, and the image analyzing device 12 compares a total amount ofsubstitute currency 120 for gaming to be present in the collection tray171 for substitute currency for gaming, which is acquired by adding anincreased amount of substitute currency 120 for gaming in the game thatis calculated based on the positions, the types, and the quantities ofthe substitute currency 120L for gaming bet by losing players, with areal total amount of the substitute currency 120 for gaming placed inthe tray 171 for substitute currency for gaming, and determines whetheror not there is a difference between the total amount and the real totalamount.

When the control device 14 determines a difference in the real totalamount of the substitute currency 120 for gaming acquired from the tray17 for substitute currency for gaming for the dealer 5 of the game table4 not corresponding to the increased/decreased amount of the substitutecurrency for gaming calculated based on the amount of substitutecurrency for gaming bet by all the players and a result ofwinning/losing of the game, the game recording device 11 assigns anindex or time to the acquired video or can reproduced with a collectionscene or a payment scene of the substitute currency 120 for gamingspecified such that the recording of the game in which the differenceoccurs can be analyzed by the game recording device 11.

In this way, the control device 14 acquires a total amount of substitutecurrency for gaming (chips) placed in the tray 17 for substitutecurrency for gaming after a settlement at the time of end of a gamethrough the image analyzing device 12. In this case, the determinationof “after the settlement” is when one of “1)” to 4)” described belowoccurs.

-   -   1) when repayment for won substitute currency 120 for gaming        (won chips) ends    -   2) when cards C used in the game are collected and are disposed        in the disposal area or the disposal slot of the table    -   3) when a predetermined button accompanying the winning/losing        result determining device is pressed    -   4) when the marker 43 representing winning/losing is returned to        the original state

In the management system of the table game, the management controldevice images the positions, the types, and the quantities of substitutecurrency for gaming that is placed by game participants in each gamewhen any one of 1) to 3) described below is detected:

-   -   1) when the card distributing device detects that a first card        is drawn    -   2) before and after drawing    -   3) after the management control device recognizes a dealer's bet        end sign

In addition, the control device 14 has an artificialintelligence-utilizing or deep-learning structure capable of acquiringthe position (a position for betting on the player, the banker, or thefair) and the amount (the types and quantities) of bet substitutecurrency for gaming at each player position 7 of the game table 4,comparing a winning/losing history of each player 6 and the amount (wonamount) of acquired substitute currency for gaming that can be acquiredbased on the result of winning/losing of each game with statistical dataof many (big data) games in the past, and extracting an abnormalsituation (set in the casino).

Typically, the control device 14 is included which has an artificialintelligence-utilizing or deep-learning structure capable of extractingan occurrence of a won amount of a certain amount (one million dollars)or more and an abnormal situation in which, in a play position 7 of aspecific game table 4, a state in which the amount of bet substitutecurrency for gaming is small at the time of losing a game, and theamount of bet substitute currency for gaming is large at the time ofwinning a game is continued for several games and is determined as anabnormal situation based on a comparison with statistical data (big dataor the like) of games in the past.

In addition, the control device 14 (integrated with the image analyzingdevice 12) of the fraud detecting system has a structure capable ofextracting an abnormal situation or specifying an individual player 6 atthe play position 7 at which winning of a predetermined amount of moreis acquired. In such specifying of a player 6, the image of each face isspecified with a profit and an identify number (an ID or the like)assigned thereto in the image analyzing device 12. Then, the controldevice 14 has a warning function for giving a notification of thepresence of a specific player in another game table when the specifiedplayer 6 leaves a seat and arrives at the another game table. Morespecifically, a notice is given to a pit manager managing each gametable 4 or each table staff (or a dealer), wherein further prevention ofan abnormal phenomenon is achieved.

The control device 14 includes a database recording a history ofexchange of bills K and substitute currency 120 for gaming, refers tothe database at the interval of a predetermined time or in units of oneday and determines through a comparison whether or not the amount ofsubstitute currency 120 for gaming acquired in the tray 17 forsubstitute currency for gaming for the dealer 5 of the game table 4 hasbeen increased or decreased according to a payed amount of substitutecurrency 120 for gaming corresponding to exchanged bills K or a totalamount of payment of bills K corresponding to exchanged substitutecurrency 120 for gaming.

In addition, a winning/losing history of each play position 7 and theamount (won amount) of acquired substitute currency for gaming may bemonitored without specifying an individual player 6.

In such a case, while, in a case where each player 6 leaves the seat,the player 6 cannot be tracked, an abnormal situation such as a casewhere, a state in which the amount of bet substitute currency for gamingis small at the time of losing a game at a specific play position 7 ofone game table 4, and the amount of bet substitute currency for gamingat the time of winning a game is large is continued for several games orthe like can be detected. Then, in a case where such a play position 7is detected, there is a suspicion that there is fraud or a mistake atthe play position 7. Then, by verifying a video in which the playposition 7 is imaged, a fraud or a mistake can be found.

More specifically, the camera device 2 is mounted to image at leastsubstitute currency 120 for gaming placed in the bet area 8 of the gametable 4. The image analyzing device 12 analyzes images captured by thecamera device 2 and detects a position among the positions of theplayer, the banker, and the tie of the bet area 8 at which substitutecurrency for gaming is placed for each user position 7 and the amount ofthe placed substitute currency for gaming. In addition, the carddistributing device 3 also functions as a winning/losing resultdetermining device and determines a result of winning/losing of a game.The control device 14, based on the position (the player, the banker, orthe tie) inside the bet area 8 at which the substitute currency 120 forgaming is placed and the result of winning/losing of the game, recordsmonitors) a winning/losing history for each play position 7 and theamount (an acquired amount of the substitute currency for gaming) of thesubstitute currency for gaming that has been acquired. Here, any one ofthe winning/losing history and the acquired amount of the substitutecurrency for gaming may be recorded. In a case where the winning/losinghistory/or the acquired amount of the substitute currency for gaming isin an abnormal situation (set in the casino) when compared with thestatistical data of many (big data) games in the past, the controldevice 14 specifies this player position 7 as a play position at which asuspicion of fraud is present.

In a case where there is a suspicion of fraud for a specific playerposition 7, the fraud detecting system may be configured to generate analarm (light, a sound, or a vibration) such that at least the dealergets near at the time point. In this way, a game thereafter is stoppedat least at the place or the like, and the continuation of fraud can beblocked. In addition, information representing a suspicion of fraud maybe added to a video that is captured and recorded by the camera device2. Accordingly, by checking the video, the cause of the suspicion offraud can be investigated.

The fraud detecting system in a game house including a game tableaccording to this embodiment further has a function of performing aninspection at the time of exchange of bills and substitute currency forgaming that is frequently performed in the game table 4. In a game housesuch as a casino, before a game, a player 6 exchanges bills (cash or thelike) and substitute currency for gaming at a predetermined substitutecurrency for gaming clearing house. However, when all the substitutecurrency for gaming is used, the player 6 can continue the game byexchanging cash (bills) with substitute currency 120 for gaming on thegame table (a Baccarat table or the like) without leaving the seat fromthe game table 4. However, here, there is a chance for fraud between thedealer 5 and the player. The exchange of cash (bills) for substitutecurrency 120 for gaming on a game table (for example, a Baccarat tableor the like) needs to be performed when a game does not advance. Inorder to determine winning/losing of a game, the card distributingdevice 3 can detect the start of dealing of cards and the end of dealing(a time period for determining winning/losing). For this reason, thecard distributing device 3 detects a situation other than thedistribution (dealing) of cards, and the control device 14 detectsexchange of bills and substitute currency 120 for gaming on the gametable 4 in a situation other than the dealing of cards (illustrated inFIG. 5).

Being in the middle of the dealing (or any other situation) of cards canbe detected based on information acquired from the operation of the carddistributing device 3 or the dealer 5.

The control device 14 can recognize the quantity and the amount of billsby performing an image analysis of the surfaces of the bills K. Inaddition, in the game table 4, it is determined whether or not bills Kto be exchanged for substitute currency 120 for gaming are genuine bydetecting genuine marks G of the bills by emitting black light. Asillustrated in FIG. 5, the control device 14 has an artificialintelligence-utilizing or deep-learning structure verifying the genuinemarks G through an image analysis, recognizing a total amount of genuinebills, being capable of recognizing a total amount of substitutecurrency for gaming even in a state in which a plurality of substitutecurrency for gaming come out onto the game table as an exchange targetis hidden due to a blind area of the camera device 2, comparing a totalamount of the bills K come out onto the game table 4 from a player witha total amount of the substitute currency 120 for gaming come out fromthe dealer 5, and being capable of determining whether or not both theamounts match each other.

The control device 14 has an artificial intelligence-utilizing ordeep-leaning structure capable of determining whether or not a totalamount of substitute currency 120 for gaming placed in the tray 17 forsubstitute currency for gaming for the dealer 5 of the game table 4 hasbeen increased/decreased according to a paid amount of substitutecurrency for gaming corresponding to the exchanged bills after asettlement through exchange of the bills and the substitute currency forgaming. A case may be considered as well in which the total amount ofthe substitute currency 120 for gaming placed in the tray 17 forsubstitute currency for gaming for the dealer 5 is constantly acquiredin advance by using RFIDs of substitute currency 120 for gaming or thelike. In addition, the total amount of the substitute currency 120 forgaming housed in the tray 17 for substitute currency for gaming can bedetected by imaging the tray 17 for substitute currency for gaminghousing the substitute currency 120 for gaming by using the cameradevice 2 and analyzing the image using the image analyzing device 12.

In addition, the control device 14 detects whether an increase/decreasein the amount of the substitute currency 120 for gaming present insidethe tray 17 for substitute currency for gaming before and after theexchange of bills and the substitute currency for gaming matches anexchange amount of the substitute currency for gaming as a result of animage analysis on the game table 4. The amount of paid bills may beinput by the dealer 5 to the control device 14 through key input or thelike or may be specified by imaging an area disposed on the game table 4in which bills are paid by using the camera device 2 and analyzing theimage using the image analyzing device 12.

As described above, the control device 14 determines whether or not adecreased amount of the substitute currency 120 for gaming from the tray17 for substitute currency for gaming according to the exchange of billsand the substitute currency for gaming matches the amount paid to thedealer 5 from players 6. In addition, the control device 14 is anintelligence-type control device capable of determining match/mismatchof an input amount (commonly, according to key input or the like) ofbills input by the dealer 5 and a calculated amount of bills that is aresult of an image analysis performed by the image analyzing device 12after the settlement through the exchange of the bills and thesubstitute currency for gaming through a comparison and calculation andmay have an artificial intelligence-utilizing or deep-learningstructure.

Furthermore, the control device 14 has an artificialintelligence-utilizing or deep-learning structure capable of determiningmatch/mismatch of a total amount of bills according to the input of adealer in the game table 4 for which the dealer is responsible and atotal amount of bills according to a result of an image analysis usingthe image analyzing device 12 through a comparison and calculation.

The control device 14 determines whether or not the amount of substitutecurrency 120 for gaming perceived in the tray 17 for substitute currencyfor gaming for the dealer 5 of the game table 4 has increased/decreasedaccording to a paid amount of substitute currency 120 for gamingcorresponding to exchanged bills after the exchange of the bills and thesubstitute currency 120 for gaming or a paid amount of billscorresponding to the exchanged substitute currency 120 for gamingthrough a comparison.

The control device 14 is a control device having an artificialintelligence-utilizing or deep-learning structure capable of acquiringinformation of the types and the quantities of the substitute currency120 for gaming even in a state in which a part of or the whole one unitof substitute currency for gaming is hidden when the types and thequantities of the substitute currency 120 for gaming are determined.

A management system according to a second embodiment relates to amanagement system of table games in a game house.

In a game house such as a casino, there are various attempts preventingdealer's mistakes in handling substitute currency for gaming (substitutecurrency for gaming). A game house includes monitoring cameras used formonitoring dealer's mistakes in handling substitute currency for gaming,and such mistakes are prevented using a determination of mistakes andfraud according to collection and repayment of substitute currency forgaming that are different from a result of winning/losing based onimages acquired using the monitoring cameras and the like.

Meanwhile, in order to acquire the quantity and a total amount ofsubstitute currency for gaming, it has been proposed to acquire theamount of the substitute currency for gaming by attaching an IC tag toeach substitute currency for gaming.

In a card game monitoring system disclosed in PCT ApplicationPublication No. PCT/JP2015/000171, it is determined whether or notsubstitute currency for gaming place on a game table is collected orre-payed according to a result of winning/losing by performing an imageanalysis of movement of the substitute currency for gaming, andmonitoring of dealer's mistakes in handling the substitute currency forgaming is performed.

In game houses such as casinos, while substitute currency for gaming ispiled to have a high volume and is placed on a game table, there is aproblem in that a total amount cannot be correctly read by a readingdevice for IC tags disposed under the game table, and, when thesensitivity of the reading device is increased, substitute currency orgaming placed at a different position (winning/losing depends on theposition) is added, and there is a problem in that a total amount ofsubstitute currency for gaming at each position cannot be perceived. Inaddition, conventionally, as illustrated in FIG. 7, the pattern ofsubstitute currency for gaming (substitute currency for gaming) 9 iscomplicated, and, when a plurality of substitute currency for gaming arepiled, there is a problem in that the quantity of such a pile cannot beaccurately acquired using a camera.

Furthermore, fraud on a game table has been advanced, and there is a newproblem in that fraud using an advanced betting method or the like thatcannot be found in simple detection of a large winning amount on a gametable or the like cannot be found by using a camera.

In addition, it is necessary for a dealer to collect or re-paidsubstitute currency for gaming placed on a game table according to aresult of winning/losing. In a case this is to be determined byperforming an image analysis of the substitute currency for gaming,since the pattern of the substitute currency for gaming (substitutecurrency for gaming) is complicated, there is a problem in that itcannot be determined whether or not a dealer correctly performsre-payment when substitute currency for gaming corresponding to the betsubstitute currency for gaming is re-payed by using a currently-existingpractical image analyzing technology, and the prevention of mistakes isnot sufficient.

In order to solve the various problems described above, a managementsystem of table games according to this embodiment includes: a carddistributing device that determines and displays a result ofwinning/losing of each game in a game table; a measurement device thatmeasures the types and the quantities of substitute currency for gamingplace on the game table by using a camera; and a management controldevice that specifies and stores the position, the types, and thequantity of substitute currency for gaming placed on the game table by agame participant by using a result of the measurement performed by themeasurement device in each game. The substitute currency for gaming hasa configuration in which a plurality of plastic layers of differentcolors are stacked, at least a coloring layer is included in the middle,and a stripe pattern in a stacking direction is formed on a side face byemploying a multi-layer structure in which white layers or thin-colorlayers are stacked on both sides of the coloring layer disposed in themiddle, and the type of the substitute currency for gaming can bespecified by using the coloring layer. The management control device hascalculation functions of determining a winner and a loser amongparticipants in each game by using a result of winning/losing acquiredfrom the card distributing device and a result of the measurement of theposition, the types, and the quantities of the substitute currency forgaming placed by each game participant and calculating the balance ofthe casino side in the game table for each game.

In addition, in the management system, the management control device hasa structure including a function of determining the quantity of thesubstitute currency for gaming by measuring the number of coloringlayers, the white layers, or the thin-color layers of the substitutecurrency for gaming placed by each game participant.

In order to solve the various problems, substitute currency for gamingaccording to this embodiment has a configuration in which a plurality ofplastic layers of different colors are stacked, at least a coloringlayer is included in the middle, and a stripe pattern in a stackingdirection is formed on a side face by stacking white layers orthin-color layers on both sides of the coloring layer, and the type ofthe substitute currency for gaming can be specified by using thecoloring layer.

In addition, in the substitute currency for gaming, on the surface ofthe white layer or the thin-color layer, a print representing the typeof the substitute currency for gaming is formed, transparent layers aredisposed in outermost layers, and each interlayer is thermos-compressedto form a structure of at least five layers.

In addition, in the substitute currency for gaming, marks using UV inkor ink (carbon black ink) absorbing infrared rays are arranged on thesurfaces of the white-color layers or the thin-color layers, orembossing processing is performed for the transparent layer of theoutermost layer, or R processing is performed for the ends of thetransparent layers of the outermost layers, or the coloring layer isformed by a plurality of layers, and RFIDs may be built in the coloringlayers.

In order to solve the various problems described above, an inspectiondevice inspecting substitute currency for gaming according to thisembodiment includes: a passage including an inlet and an output throughwhich the substitute currency for gaming can pass in a radial direction;a gaming substitute currency type determining device that determines acolor of the stripe in the staking direction of the side face by imagingthe side face of the substitute currency for gaming passing through thepassage; a mark reading device that reads a mark, which is formed usingthe UV ink or the ink (carbon black ink) absorbing infrared rays,arranged on the surface of the passing substitute currency for gaming; aprint inspecting device that reads a print representing the typearranged on the surface of the substitute currency for gaming in avertical direction with respect to the passage; and a control device ofthe whole device. The control device is configured to inspect whether ornot the type of the substitute currency for gaming determined by thegaming substitute currency type determining device matches a content ofthe print representing the type acquired by the print inspecting device.

According to the system of this embodiment, even in a case where manysubstitute currencies for gaming (substitute currency for gaming) arepiled up, the quantity of the substitute currencies for gaming can bedetermined, and a total amount of relatively overlapping substitutecurrency for gaming can be acquired based on the position and the color.

Hereinafter, a management system of table games in a game houseincluding a game table according to an embodiment of the presentinvention will be described. FIG. 6 is a diagram that illustrates anoverview of the whole system. The management system of table games in agame house including a plurality of game tables 4 includes: ameasurement device 19 including an image analyzing device 18 thatrecords a state of process of a game played in the game table 4 as avideo including game participants 6 and a dealer 5 through a pluralityof camera devices 2 and performs an image analysis of the recorded videoof the state of process of the game; and a card distributing device 3that determines and displays a result of winning/losing of each game inthe game table 4. The card distributing device 3 is a so-calledelectronic shooter that has already been used by persons skilled in theart and has rules of a game programmed in advance and has a structurecapable of determining winning/losing of a game by reading informationof distributed cards C. For example, in a Baccarat game, winning of thebaker, winning of a player, or tie (drawn) is determined basically basedon the ranks of two to three cards, and a determination result (a resultof winning/losing) is displayed in a result display lamp 13.

The management control device 14 reads information (ranks and suits) ofcards C acquired from the card distributing device 3 and determines aresult of winning/losing of each game and determines a winner 6W and aloser 6L among the participants 6 in each game by using a result ofmeasurement of the position, the types, and the quantities of substitutecurrency 120 for gaming placed by the game participants 6.

In addition, the management control device 14 has a calculation functionof calculating a balance (an amount acquired by subtracting a totalamount of substitute currency 120 for gaming that is re-paid to a winner6W among the participants 6 from a total amount of substitute currency120 for gaming bet by the loser 6L) of the casino side in the game table1 for each game.

The image analyzing device 18, the measurement device 19, and themanagement control device 14 of this detection system have a structureintegrally including a computer formed as one body or by a plurality ofconfigurations, a program, and a memory.

Next, details of substitute currency for gaming used in this detectionsystem will be described. FIG. 8 is a front cross-sectional view ofsubstitute currency 120 for gaming used in this detection system. Thesubstitute currency 120 for gaming has a multi-layer structure in whicha plurality of plastic layers having different colors are stacked, acoloring layer 121 is included at least in the middle, and white layers122 or thin-color layers (while not illustrated in the drawing, thelayers may be layers of a color that is thinner than that of thecoloring layer 121) are stacked on both sides of the coloring layer 121of the middle.

In this way, by employing a multi-layer structure in which the coloringlayer 121 is included, and white layers 122 or thin-color layers (whilenot illustrated in the drawing, the layers may be layers of a color thatis thinner than that of the coloring layer 121) are stacked on bothsides of the coloring layer 121 of this middle, as illustrated in FIG.9A, a stripe pattern is formed on the side face in the stackingdirection, and the type of the substitute currency 120 for gaming can bespecified by changing the color (red, green, yellow, blue, or the like)of the coloring layer 121 for each type (10 points, 20 points, 100points, 1000 points, and the like) of the substitute currency 120 forgaming.

The substitute currency 120 for gaming is configured as a structure bodyincluding the coloring layer 121 and the white layer 122 or thethin-color layer at least in the outer appearance to form a stripepattern in the axial direction on the side face and has a configurationenabling the type of the substitute currency 120 for gaming to bespecified using the coloring layer 121. While FIGS. 10A and 10Billustrate different examples, in the examples, the coloring layer 121and the white layer 122 or the thin-color layer are formed throughinjection molding, and so-called two-color molding is used in which,first, the coloring layer 121 is molded inside a die for molding (notillustrated in the drawing), and thereafter, the white layer 122 or thethin-color layer is molded.

In addition, as illustrated in FIG. 9B, in the substitute currency 120for gaming, prints 123 (100 points or the like) representing the type ofthe substitute currency 120 for gaming are formed on the surfaces (theupper face and the lower face) of the white layer 122. As illustrated inFIG. 8, the transparent layers 124 are disposed in the outermost layers,and each interlayer is thermos-compressed, and a structure of at leastfive layers is formed. Such substitute currency 120 for gaming is formedby using a plastic material having a thin long shape, and layers (thecoloring layer 121, the white layer 122, and the transparent layer 124)are thermo-compressed to form a closely adhering state (a structure offive layers or the like) in the state of a long length, and thereafter,holes having a circular shape, a rectangular shape, or the like areformed therein through press or the like.

When a hole is formed through the press, die of mold for punching, andthe size of punching are designed, and R processing (round angle) isperformed for the ends of the transparent layer 124 of the outermostlayer.

That is, in order to manufacture the substitute currency 120 for gaming,first, a plate-shaped coloring layer 121 formed using plastic and aplate shaped white layer 122 or a thin-color layer formed using plasticare stacked, and a stacked structure body configured by a plurality ofplastic layers is formed. Then, drawing patterns are printed on theupper face and the lower face of this stacked structure body, andtransparent layers 124 are formed thereon. Then, the layers of thestacked structure body and the transparent layers 124 are heated andpressed to be heated and welded, whereby a substitute currency originalplate is generated. Then, punching processing is performed for thesubstitute currency original plate acquired in this way, whereby aplurality of substitute currencies 120 for gaming having a predeterminedshape are acquired. When this punching processing is performed, Rprocessing is performed for upper and lower angles of the substitutecurrency 120 for gaming using a mold.

In addition, in the substitute currency 120 for gaming, face codes usingthe UV ink or ink (carbon black ink) absorbing an infrared rays arearranged on the surface of the white layer 122 (see FIG. 9B). This facecodes represent the authenticity of the substitute currency 120 forgaming, and, when ultraviolet rays (or infrared rays) are emittedthereto, a mark is visible to the eyes, and a combination of the formand the number of the marks represents the authenticity. FIG. 11 is aperspective view of a state in which the substitute currency 120 forgaming is stacked up, and a face code M is acquired by combining a longcode L and a short code S. In the outermost layers, while transparentlayers (print layers) 124 are thermally compressed or formed as coatinglayers to cover the print 123 and the face code, embossing processing isperformed for these transparent layers 124, and the close adherencebetween the substitute currencies 120 for gaming is prevented. Inaddition, in this embodiment, while an example has been described inwhich face codes are printed on the surfaces of the white layers 122,instead of the face codes or together with the face codes, one or bothof a security mark and an optically variable device (OVD) may beprinted.

The R processing (R) is performed for the ends of the transparent layers(print layer) 124 of the outermost layer for which the print 123 (100points or the like), and in the punching process of the substitutecurrency 120 for gaming, the surfaces of the white layers 122 areprevented from being deformed to appear on the side face. In addition,it is prevented that a sharp end remains in the substitute currency 120for gaming and damages the hands or the other substitute currency 120for gaming.

The coloring layer 121, as illustrated in FIG. 8, may be formed by aplurality of colored layers (three layers in the case illustrated inFIG. 8). Since the plurality of colored layers (three layers in the caseillustrated in FIG. 8) are thermos-compressed, a state in which thethree-layer structure can be visually observed, as illustrated in FIG.8, is not formed. However, three layers are illustrated in FIG. 8 fordescription. In addition, in a middle layer among the three layers ofthe coloring layer 121, a partly hollowed portion B is arranged, and anRFID 125 is built therein.

In addition, without arranging the hollowed portion B in the coloringlayer 121, the RFID 125 may be built in the substitute currency 120 forgaming by arranging the RFID 125 between the coloring layer 121 having aflat surface and the white layer 122 having a flat surface andperforming thermos-compressing of the coloring layer 121 and the whitelayer 122 as it is. By configuring at least one of the coloring layer121 and the white layer 122 using a material such as plastic that can bethermally deformed, out of the coloring layer 121 and the white layer122 having the RFID 125 interposed therebetween through thermalcompression, a plastic layer is thermally deformed, and accordingly, theRFID 125 is tightly fixed between such layers without arranging thehollowed portion B.

FIG. 12 is a perspective explanatory photographic diagram thatillustrates a state in which substitute currency for gaming of differenttypes are piled up. The management control device 14 images substitutecurrency 120 for gaming placed on the game table 1 by the gameparticipant 6 by using the camera device 2 and measures each area 8(whether the bet is on the banker, the player, the pair, or the tie) inwhich the substitute currency 120 for gaming is placed by using themeasurement device 19 including the image analyzing device 18, and themeasurement device 19 (by using information acquired by the imageanalyzing device 18) analyzes and measures the number and the colors ofcoloring layers 121 (or the thin-color layers) or white layers 122 ofthe substitute currency 120 for gaming that is stacked in each area anddetermines the types and the quantities of the substitute currency 120for gaming. The management control device 14 performs control of thecamera device 2 such that imaging using the camera device 2 is performedwhen the first card is drawn from the card distributing device, beforeand after the drawing, or after a dealer's sign representing the end ofbetting.

The management control device 14 may be a control device having anartificial intelligence-utilizing or deep learning structure. Themanagement control device 14 can perceive the position 8 (a positionbetting on a player, a banker, or a pair), the types (a value of adifferent amount is assigned to the substitute currency 120 for gamingfor each color), and the quantities of the substitute currency 120 forgaming that is bet by each participant 6 through the camera device 2 andthe image analyzing device 18. The artificial intelligence-utilizingcomputer or control system can perceive the position 8 (a positionbetting on a player, a banker, or a pair), the types (a value of adifferent amount is assigned to the substitute currency for gaming foreach color), and the quantities of the substitute currency 120 forgaming by using a self-learning function or the like in thedeep-learning (structure) technology, and thus, according to a result ofwinning/losing of a game determined by the card distributing device 3 ineach game, determines whether or not the collection (denoted using anarrow L) of substitute currency 120 for gaming bet by a losingparticipant 6L and the re-payment (payment (120W)) for winningsubstitute currency 120 for gaming for the winning game participant 6Ware appropriately performed according to a result of winning/failure ofthe game in each game by analyzing a video of the state of progress ofthe game by using the management control device 14 through the imageanalyzing device 18.

In such a case, as illustrated in FIG. 11 (compared to conventionalsubstitute currency for gaming illustrated in FIG. 7), a stackedmulti-layer structure is formed, and a stripe pattern is formed on theside face in the stacking direction, and accordingly, the measurementdevice 19 including the image analyzing device 18 can accurately performthe measurement of the types and the quantities of substitute currencyfor gaming in an easy manner. In addition, by using an artificialintelligence-utilizing computer or control system and a deep-learning(structure) technology, the analysis and the determination of the imagecan be performed more accurately. The artificial intelligence-utilizingcomputer or control system and the deep-learning (structure) technologyare known to persons skilled in the art and can be used, and thus,detailed description thereof will be abbreviated.

The management control device 14 can analyze and perceive a total amountof substitute currency 120 for gaming in the tray 17 for substitutecurrency for gaming for the dealer 5 of the game table 4 by using theimage analyzing device 18 and can determine through a comparison andcalculation whether or not a total amount of the substitute currency 120for gaming placed inside the tray 17 for substitute currency for gaminghas been increased/decreased according to the collection of the losingsubstitute currency 120 for gaming bet by each game participant 6 andthe amount of the payment 120W for winning substitute currency forgaming to the winning game participant 6W after the game ends and issettled based on the result of winning/losing of the game. The totalamount of the substitute currency 120 for gaming in the tray 17 forsubstitute currency for gaming may be constantly acquired by using meanssuch as RFIDs, and it is determined whether or not theincreased/decreased amount is correct by the management control device14 by analyzing a video of the state of progress of the game through theimage analyzing device 18. For these, an artificialintelligence-utilizing or deep-learning structure may be utilized.

In addition, the management control device 14 may have an artificialintelligence-utilizing or deep-learning structure capable of acquiringthe position (a position for betting on the player, the banker, or thefair) and the amount (the types and quantities) of bet substitutecurrency for gaming at each player position 7 of the game table 4,comparing a winning/losing history of each player 6 and the amount (wonamount) of acquired substitute currency for gaming that can be acquiredbased on the result of winning/losing of each game with statistical dataof many (big data) games in the past, and extracting an abnormalsituation (set in the casino). Typically, the management control device14 is included which has an artificial intelligence-utilizing ordeep-learning structure capable of extracting an occurrence of a wonamount of a certain amount (one million dollars) or more and an abnormalsituation in which, in a play position 7 of a specific game table 4, astate in which the amount of bet substitute currency for gaming is smallat the time of losing a game, and the amount of bet substitute currencyfor gaming is large at the time of winning a game is continued forseveral games and is determined as an abnormal situation based on acomparison with statistical data (big data or the like) of games in thepast.

The total amount of the substitute currency 120 for gaming in the tray17 for substitute currency for gaming for the dealer 5 of the game table4 is settled for the substitute currency 120 for gaming bet by eachparticipant 6 after each game, and the management control device 14 hasa structure capable of determining through a comparison and calculationwhether or not an increase/decrease in the substitute currency forgaming that corresponds to a settlement is correct after the settlement.

In a plurality of cashiers 60 present in a game house, the substitutecurrency 120 for gaming is exchanged with cash 61 paid by a gameparticipant 6, and, in each cashier 60, substitute currency 120 forgaming is stored in a storage 62 storing the substitute currency 120 forgaming. In each cashier 60 of a game house, substitute currency 120 forgaming brought by a game participant 6 is refunded into cash 61. In thegame table 4, substitute currency 120 for gaming is stored in a gametable gaming substitute currency tray 17, and a dealer 5 collectssubstitute currency 120 for gaming bet by a game participant 6 who haslost the game from the table 4 in each game, returns the collectedsubstitute currency 120 for gaming to the game table gaming substitutecurrency tray 17, and then re-pays the substitute currency 120 forgaming to a game participant 6 who has won each game. All such exchangesbetween a game participant 6 and a cashier 60 of a game table or adealer 5 are imaged and recorded by all the camera devices 2. In thestorage 62 or the game table gaming substitute currency tray 17, whenthere is exchange of substitute currency 120 for gaming with a gameparticipant 6, the substitute currency 120 for gaming stored in thestorage 62 or the game table gaming substitute currency tray 17increases or decreases. The types and the quantities of the substitutecurrency 120 for gaming stored in the game table gaming substitutecurrency tray 17 and the storage 62 are monitored at predeterminedtiming or constantly by the ID reading device 53 and the gamingsubstitute currency determining device 52 through the camera device 2.The management control device 50 stores the side IDs 126 of all thesubstitute currency 120 for gaming assumed to be used in a game house inthe database 51 in advance (the side IDs 126 of all the substitutecurrency 120 for gaming assumed to be used in the game house areregistered).

In addition, also in this embodiment, the gaming substitute currencytray 17, as illustrated in FIGS. 14A and 14B, may be configured by anupper gaming substitute currency tray 17 a and a lower gaming substitutecurrency tray 17 b of upper/lower two stages. In such a case, in thestate illustrated in FIG. 14A, the upper gaming substitute currency tray17 a can be imaged by the camera device 2, and, in the state illustratedin FIG. 14B, the lower gaming substitute currency tray 17 b can beimaged by the camera device 2. In the state illustrated in FIG. 14B,additionally, the upper gaming substitute currency tray 17 a and thelower gaming substitute currency tray 17 b can be imaged by the cameradevice 2 c simultaneously and also in an individually-identifiablestate. In addition, in the state illustrated in FIG. 14B, the uppergaming substitute currency tray 17 a and the lower gaming substitutecurrency tray 17 b may be separately imaged. Each of the camera devices2 and 2 c may include a single visible-light camera or a single infraredray camera corresponding to ink printed for the side ID 126 or a cameracapable of performing switching among a plurality of functions of avisible-light camera and an infrared-ray camera corresponding to theprinted ink.

In this way, in the game house, by using the database 51, the managementcontrol device 50 managing the side IDs 126 associated with substitutecurrency 120 for gaming manages all the side IDs 126 of at leastsubstitute currency 120 for gaming present in the game table gamingsubstitute currency tray 17 and the storage 62 in the database 51together with the presence information thereof (the storage 62, the gametable gaming substitute currency tray 17, in the middle of moving from abackyard (not illustrated in the drawing), held by a game participant 6,or the like). The management control device 50 specifies all thesubstitute currency 120 for gaming disposed in the game table gamingsubstitute currency tray 17 and the storage 62 by using the side IDs 126at predetermined timing or constantly, searches the database 51, anddetermines the following events through the search of the database 51:

-   -   1) A side ID 126 that has not been present (or not present) in        the database 51 is determined to be newly present.    -   2) Two or more same IDs are determined to be present.

The management control device 50 has a function of generating an errorsignal representing an abnormality and giving a notification to amanagement division or a security division 54 of the game house when thesituation of 1) or 2) described above is present. The management controldevice 50 specifies all the substitute currency 120 for gaming disposedin the game table gaming substitute currency tray 17 and the storage 62at predetermined timing or constantly by using the side IDs 126 andstores all the substitute currency 120 for gaming in the database 51 andthus, can determine that 1) a side ID 126 that has not been present (ornot present) in the database 51 is newly present and 2) two or more sameIDs are present.

In addition, when there is a change in the presence of the substitutecurrency 120 for gaming at least in the game table gaming substitutecurrency tray 17 and the storage 62, the management control device 50records time or a place (the storage 62, the game table gamingsubstitute currency tray 17, or the like) at which the change is presentin the database 51 in association with the side ID 126 and, as a resultof the search of the database 51, when there is a situation in which twoor more same side IDs 126 are present, extracts the side ID 126 andinformation of time or a place recorded in the database 51 inassociation with the side ID 126 from the database 51 and stores theside ID and the information that have been extracted, and thus, time atwhich substitute currency 120 for gaming to which the side ID 126 isattached, which has been detected first (used first or cashed),enters/exits the game table gaming substitute currency tray 17 or thestorage 13 or a place of the game table gaming substitute currency tray17 or the storage 13 in which the substitute currency 120 for gaming isstored can be specified by using the database 51. When the time and theplace can be specified, a suspicious person for the use of unjustsubstitute currency 120 for gaming or the like can be specified from therecorded video of the camera device 2.

In this management system of substitute currency for gaming, themanagement control device 50 can specify the types and the quantities ofthe substitute currency 120 for gaming bet on the bet area 8 of the gametable 4 by using the ID reading device 53. The substitute currency 120for gaming of the bet area 8 is imaged by the camera device 2 b thatparticularly images the bet area 8 and, also for the side ID 126 of thesubstitute currency 120 for gaming present on the bet area 8 of the gametable 4, determines the following events by searching the database 51:

-   -   1) A side ID 126 that has not been present in the database 51 is        newly present in the bet area 16.    -   2) Two or more same IDs are present.

The management control device 50 has a function of generating an errorsignal when a situation of 1) or 2) described above is present.

The management control device 50 of this system, the ID reading device53 disposed inside, and the gaming substitute currency determiningdevice 52 specifying the types and the quantities of substitute currency120 for gaming have a structure integrally including a computer formedas one body or by a plurality of configurations, a program, and amemory.

Next, details of substitute currency 120 for gaming (so-calledsubstitute currency for gaming) used in this system will be described.FIG. 17 is a side view of substitute currency 120 for gaming used inthis system, the substitute currency 120 for gaming is formed bystacking a plurality of plate-shaped plastic layers having differentcolors, forming the plastic layers to be integrated using a means ofthermo-compressing or the like, and then, punching holes in the shapesof circles and quadrangles. The substitute currency 120 for gamingmanufactured in this way has a multi-layer structure in which a coloringlayer 121 is included at least in the middle, and white layers 122 orthin-color layers (may be layers of a color thinner than that of thecoloring layer 121; not illustrated in the drawing) are stacked on bothsides (in FIG. 17, the upper and lower sides) of the coloring layer 121disposed in the middle. In this way, by employing the multi-layerstructure in which the coloring layer 121 is included, and the whitelayers 122 or the thin-color layers (may be layers of a color thinnerthan that of the coloring layer 121; not illustrated in the drawing) arestacked on both sides of the coloring layer 121 disposed in the middle,as illustrated in FIG. 17, a stripe pattern (in the stacking direction)when seen from the side face is formed, and, by changing the color (red,green, yellow, blue, or the like) of the coloring layer 121 for eachtype (10 points, 20 points, 100 points, 1000 points, and the like) ofthe substitute currency 120 for gaming, the type of the substitutecurrency 120 for gaming can be specified.

In addition, as illustrated in FIG. 17, in the substitute currency 120for gaming, a side ID 126 representing the type of substitute currency120 for gaming is applied to the side faces of the white layers 122.

In the outermost layers, transparent layers 124 are arranged, and eachinterlayer is thermo-compressed to form a structure of at least fivelayers. Such substitute currency 120 for gaming is formed by using aplastic material having a thin long shape, and layers (at least thecoloring layer 121 and the white layers 122) are thermo-compressed toform a closely adhering state (the structure of five layers or the like)in the state of a long length, and thereafter, holes having a circularshape, a rectangular shape, or the like are formed therein through pressor the like.

When a hole is formed through the press, die of mold for punching, andthe size of punching are designed, and R processing (round angle) isperformed for the ends of the transparent layer 124 of the outermostlayer.

The transparent layers 124 may be a coat layer of varnish. The side ID126 is attached to at least three positions on the side face of thesubstitute currency 120 for gaming. The side ID 126 is attached throughinkjet printing using ink that is visible for visible light.

Particularly, in this embodiment, the side ID 126 is configured to beattached as presence/absence of marks C of a plurality of rows and aplurality of columns. In the marks C of the plurality of rows and theplurality of columns, as illustrated in FIG. 17, upper and lower marks Care paired to configure a code, and a code of ten digits is formed inthe case illustrated in FIG. 17. A configuration in which upper andlower marks C are paired to configure a code (four types) is illustratedin FIG. 18. A letter “Y” disposed to the side of marks C is anidentification mark used for identifying upper and lower sides of amark. A code configured by marks C is configured to specify apredetermined combination of marks C. As a result, in the exampleillustrated in FIG. 18, there are four types of combination of the marksC of upper and lower two columns, and, by printing these in ten columns,four to the power of 10 codes can be configured. Since there are fourtypes of a 10-digit code, 4 to the power of 10 codes are acquired, andaccordingly, the side IDs 126 of substitute currency 120 for gaming canbe sufficiently assigned.

The substitute currency 120 for gaming forms a stripe pattern on theside face in the stacking direction by employing a multi-layer structurein which a plurality of plastic layers having different colors arestacked, the coloring layer 121 is included at least in one layer, thewhite layers 122 or the thin-color layers are stacked on a further outerside than the coloring layer 121 and has a configuration enabling thetype of the substitute currency 120 for gaming to be specified using thecoloring layer 121. The side IDs 126 are disposed at least threepositions (preferably, six positions) on the side face of the whitelayer 122 or the thin-color layer, and, in this example, six side IDsare disposed at a predetermined interval of 60 degrees in the rotationdirection (circumferential direction). The side IDs 126 individuallyidentifiable (different for each one) are attached to substitutecurrency 120 for gaming, and the side IDs 126 are disposed at apredetermined interval of 60 degrees in the rotation direction(circumferential direction) such that the side ID is necessarily seenfrom the lateral side. The side IDs 126 attached to the substitutecurrency 120 for gaming are read by the ID reading device 53 describedabove. The type, the manufacturing information, and the like ofsubstitute currency 120 for gaming can be specified by reading the sideID 126 by using the ID reading device 53, and a configuration in whichthe side ID 126 can be managed in the database 51 is formed. In thisembodiment, the side IDs 126 are attached using ink (visible ink) thatis visible for visible light through inkjet printing. The side IDs 126may be printed using at least one or a combination of ink (ink absorbinginfrared rays) that is not visible for visible light and ink (includinga side ID that is very small and is difficult to see) that is visiblefor at least visible light. In addition, the side IDs 126 may be printedby combining a plurality of such ink of a plurality of types. The IDreading device 53 includes at least a plurality of cameras (that is, avisible-light camera in a case where ink is visible ink, an infrared-raycamera in a case where ink is infrared reactive ink, and an ultravioletcamera in a case where ink is UV ink (UV radiator and a visible-lightcamera)) corresponding to the ink used for printing the side ID 126 orincludes a camera capable of performing switching among a plurality offunctions of cameras (a visible-light camera, an infrared ray camera,and an ultraviolet ray camera (an UV radiator and a visible-light cameraor the like)) corresponding to the ink.

In the case illustrated in FIG. 19, in substitute currency 120-1 forgaming, side IDs 126 are printed using ink (ink absorbing infrared rays)that is not visible for visible light. In substitute currency 120-2 forgaming, marks C of a plurality of rows and a plurality of columns areprinted using ink that is seen dark for visible light. In substitutecurrency 120-3 for gaming, additionally, marks C are printed using inkseen dark for visible light also between the side IDs 126, and the sideIDs 126 are configured to dissolve in the design not to be visuallydistinguished. In substitute currency 120-4 for gaming, a start pointand an end point of the side ID 126 are represented by a mark Cfrepresenting the end. When the substitute currencies 120-1 to 120-4 forgaming are seen using an infrared-ray camera, ink absorbing infraredrays absorbs infrared rays to be seen dark, and the substitutecurrencies 120-1 to 120-4 for gaming can be imaged in a state(represented as the substitute currency 120-5 for gaming) in which theside ID 126 can be read. In addition, the upper and lower sides of theside ID 126 are illustrated using a mark CL representing the upper andlower sides. A relation between the upper and lower sides of the mark isas illustrated in FIG. 17. In addition, the side IDs 126 may be printedusing a combination of ink that is visible for visible light and aninfrared ray absorption ink.

The side IDs 126 attached to the substitute currency 120 for gaming areread by the ID reading device 53 described above, and the ID readingdevice 53 can read the substitute currency 120 for gaming held in thestorage 62 of a cashier of a game house and the game table gamingsubstitute currency tray 17 of the game table, and actually, asillustrated in FIG. 20A, when the substitute currency 120 for gaming isstacked horizontally, the side IDs 126 can be read. In addition, thesubstitute currency 120 for gaming stacked in the bet area 8 or thelike, as illustrated in FIG. 20B, can be also read.

Furthermore, in the substitute currency 120 for gaming, a face codeusing UV ink or ink (carbon black ink) absorbing infrared rays isarranged on the surface (X) of the white layer 122 (see FIG. 9B).

This face code represents authenticity of substitute currency 120 forgaming, and, when ultraviolet rays (or infrared rays) hit the face code,the face code becomes visible to the eyes and represents authenticitybased on a combination of the forms and a number. While the transparentlayers (print layers) 124 are thermos-compressed or coated in theoutermost layers to cover a print 123 (100 points or the like) used forspecifying a game house and a face code disposed on the surface,embossing process or varnish processing is performed for the transparentlayers 124, and the substitute currency 120 for gaming is prevented fromadhering to each other and is caused to slide well. In the substitutecurrency 120 for gaming, a circular recess 127 is arranged at the centerof each of the upper and lower faces.

According to the recesses 127, the substitute currency 120 for gaming isprevented from being adhere to each other, and, by increasing thediameter of the recesses 127, the substitute currency 120 for gaming canslide well.

The R processing (R) is performed for the ends of the transparent layers(print layers) 124 of the outermost layers for which a print 123 (100points or the like) is performed, and, in the punching process of thesubstitute currency 100 for gaming, the surfaces of the white layers 122are prevented from being deformed to appear on the side face. Inaddition, it is prevented that a sharp end remains in the substitutecurrency 100 for gaming and damages the hands or the other substitutecurrency 120 for gaming. The coloring layer 121 may be formed by coloredone layer or a plurality of layers. In addition, metal or ceramic usedfor increasing the weight may be built in a layer included in the layerof the coloring layer 121. More specifically, in the material of thelayer included in the layer of the coloring layer 121, for example,metal powders (for example, a metal oxide of one or a plurality of metaloxides of zinc oxide and titanium oxide) may be contained. In addition,a part of the coloring layer 121 is hollowed out, or a space is arrangedbetween the coloring layer 121 and the white layer 122, and an RFID maybe built therein. In such a case, as the side ID 126 of the substitutecurrency 120 for gaming, a side ID 126 according to a code using themarks C and a side ID using the RFID are used together.

In the substitute currency 120 for gaming configured in this way, thetypes and the quantities of the substitute currency 120 for gaming thatis held in the game table gaming substitute currency tray 17 and thestorage 62 are specified by the gaming substitute currency determiningdevice 52 through the camera device 2 and the ID reading device 53, andthe side IDs 126 of the substitute currency 120 for gaming present onthe game table gaming substitute currency tray 17 and the storage 62 aremanaged in the database 51 together with the presence informationthereof. In this way, at least, it is inspected whether 1) a side ID 126that has not been present in the database 51 is newly present 2) two ormore same side IDs 126 are present. By determining the occurrences ofthe situations of 1) and 2) described above by searching for all theside IDs 126, the inspection is realized.

As described above, while a game participant 6 can perform exchange ofcash 61 for substitute currency for gaming in the cashier 60, exchangeof cash 61 for substitute currency 120 for gaming can be performed alsoin the game table 4. The camera device 2 images bills placed on the gametable 4 to exchange them for substitute currency 120 for gaming. Thatis, a plurality of camera devices 2 imaging the substitute currency 120for gaming disposed on the game table 4 are arranged at differentpositions to have different heights.

The management control device 50 specifies the types and the quantitiesof substitute currency 120 for gaming to be discharged from the gamingsubstitute currency tray 17 in the exchange from bills by using a resultof imaging of bills using the camera device 2. The management controldevice 50 compares real total amounts of the substitute currency 120 forgaming housed in the gaming substitute currency tray 17 before and afterthe payment and determines whether or not this difference corresponds tothe specified types and quantities of the substitute currency 120 forgaming to be discharged.

That is, the management control device 50 determines through acomparison whether or not a total amount of the substitute currency 120for gaming perceived in the gaming substitute currency tray 17corresponds to an increase/decrease according to a paid amount of thesubstitute currency 120 for gaming corresponding to exchanged billsafter the exchange of the bills and the substitute currency 120 forgaming. In addition, when collection and re-payment according to aresult of winning/losing of a game are simultaneously performed, themanagement control device 50 determines through a comparison whether ornot the total amount corresponds to an amount of the substitute currency120 for gaming bet by all the players 6 and an increase/decrease in thesubstitute currency 120 for gaming calculated based on a result of thewinning/losing of the game.

Here, the management control device 50 is a control device having anartificial intelligence-utilizing or deep-learning structure capable ofacquiring information of the types and the quantities of the substitutecurrency 120 for gaming even in a state in which a part or whole oneunit of the substitute currency 120 for gaming is hidden when the typesand the quantities of the substitute currency 120 for gaming aremeasured and determined.

As described above, the side IDs 126 are attached to the white layers122 or the thin-color layers of the side face of the substitute currency120 for gaming at least at three or more positions spaced apart in arotation direction (circumferential direction). The types and themanufacturing information of substitute currency 120 for gaming can bespecified by reading the side IDs 126 by using the ID reading device 53.The specified information specified through measurement has aconfiguration that can be collated and managed with the database 51.

The management control device 50 may be a control device having anartificial intelligence-utilizing or deep learning structure. Themanagement control device 50 can perceive the position 8 (a positionbetting on a player, a banker, or a pair), the types (a value of adifferent amount is assigned to the substitute currency for gaming foreach color), and the quantities of the substitute currency 120 forgaming by using an artificial intelligence-utilizing type computer orcontrol system, a deep-learning (structure) technology, a self-learningfunction, or the like.

Hereinafter, a modified example of the substitute currency 120 forgaming will be described. In the modified example, on the side face ofthe substitute currency 120 for gaming, a seven-digit number is printedas the side ID 126. In the example illustrated in FIG. 21, a white layer122 is disposed in the middle, and, under the white layer, a coloringlayer 121 is disposed. A number as a mark is printed on the white layer122 disposed in the middle and configured a side ID 126. When 10 typesof combinations of numbers are printed in seven digits, 10 to the powerof 7 codes can be configured, and accordingly, the side IDs 126 ofsubstitute currency 120 for gaming can be sufficiently assigned. In thecamera device 2 and an image analysis thereof, there are cases where itis difficult to determine and read a number, a combination of marks Cdescribed in the previous embodiment is considered to be advantageous inthe image analysis.

Another inspection device 300 inspecting the substitute currency 120 forgaming will be described with reference to FIG. 22. The inspectiondevice 300 includes: a face code reading device 306 that reads a facecode M formed using UV emission ink or ink absorbing infrared raysdisposed on the surface of the substitute currency 120 for gaming; an IDreading device 307 that reads the side ID 126 of the side face; an RFIDreading device 308 that reads information of an RFID (not illustrated inthe drawing) of the substitute currency 120 for gaming; and a controldevice 207. The control device 207 is configured to inspect a relationamong the information of the side ID 126 acquired by the ID readingdevice 307, the information acquired from the face code reading device306, and the information acquired from the RFID reading device 308.There is a correct database (not illustrated in the drawing), and therelation among the information is inspected by comparing a readingresult with the database. This inspection is used for preventing theoccurrence of a defect by detecting a print error in the face code M andthe side ID 126 or for discrimination with a fake.

This example (FIG. 22) includes an extrusion device 302 that suppliessubstitute currency 120 for gaming one at each time to a reading stage309 by using an extruder 301 that in moved in the direction of an arrowZ by the extrusion device 302, and the stacked substitute currency 120for gaming is supplied from the extrusion device 302 to the readingstage 309.
